Question

Th effective resistance of two resistors connected in parallel is 0.5 ohm, if one of the resistors is of 3 ohm, find the other?

Make it quick, please urgent !!!

Answer 1

Explanation:

Aloha !

1/R=1/R¹+1/R²

1/R=1/0.5+1/3

1/R=6+1/3

1/R=7/3

R=3/7

Thank you

Answer 2

Answer:

let second resistor be R2

A/Q

1÷3+1÷R2=0.5

1÷R2=0.5-1÷3

1÷R2=.5÷3

R2=3÷5

R2=.6 ohm
